I wonder how much this actually be an issue during the season.zibby43 wrote: ↑27 Feb 2019, 21:18James Allison
"We did set-up work in the morning with Valtteri and continued with this in the early afternoon with Lewis, yielding some good results for both drivers. The race run in the afternoon, although quite considerably quicker than the last race simulation we made, was marred by front graining – something which we think, looking up and down the pit lane, could be a feature of the year. We need to make progress on graining resistance in the next couple of days, in order to make sure we have a good way of handling it by the time the racing season begins."
It's definitely intriguing. The nature of the track surface and the track temperature are two of the biggest factors in graining (the third being the compound being used, of course).dans79 wrote: ↑27 Feb 2019, 21:53I wonder how much this actually be an issue during the season.zibby43 wrote: ↑27 Feb 2019, 21:18James Allison

I'm not sure if its correct or not, but someone posted in the testing thread this morning that air temp was 6°C and the track temp was 8°C.zibby43 wrote: ↑27 Feb 2019, 22:03It's definitely intriguing.

With the warmer track temperatures this week, I was expecting to see less graining across the board. Still lingering around. Makes me start to wonder about the construction of the new compounds this year.
I could see graining as reasonable in those conditions, especially with the nature of the circuit.dans79 wrote: ↑27 Feb 2019, 22:12I'm not sure if its correct or not, but someone posted in the testing thread this morning that air temp was 6°C and the track temp was 8°C.zibby43 wrote: ↑27 Feb 2019, 22:03It's definitely intriguing.

My gut feeling remains the same: Merc is behind. I think they closed a part of the gap but there still remains a decent chunk. For now the tests reflect what the drivers are saying here. Especially Lewis' feedback. The car is better but still issues to iron out. But if any team can turn it around, it's merc! Bracing myself for a low key start to the season! Hope to be wrong though!zibby43 wrote: ↑27 Feb 2019, 21:18https://www.mercedesamgf1.com/en/merced ... barcelona/
Report: 176 laps completed on Wednesday in Barcelona
Valtteri Bottas
"It was a positive day, we did 74 laps this morning, focusing on set-up work and making some good progress. There’s a lot of data for us to go through tonight to further improve our set-up and make sure we come up with the optimal programme for tomorrow. We learned a lot today and we will make sure to learn a lot again tomorrow."
Lewis Hamilton
"We got a lot of laps today which is a good thing, but we’ve come across a few little hurdles, so we’re just working our way through them, trying to be as diligent as possible trying to understand the causes – which is exactly what testing is for. Everyone is working flat-out and I’m sure we will get there. You need days like this to be able to bring light to the things that we need to work on."

Merc’s race pace today was actually quite strong. Especially on the harder compounds (which are more representative at Barcelona).De Jokke wrote: ↑28 Feb 2019, 00:41My gut feeling remains the same: Merc is behind.

The most interesting comment imo, is this one.zibby43 wrote: ↑27 Feb 2019, 22:20Very interesting technical piece by Mark Hughes
Why Mercedes brought such a heavily revised car to Test 2

There’s no doubting that the W10 that appeared for Week 2 of testing is radically different over almost all its body surfaces to that used in the first week. This is far too big an upgrade to have been a reaction to any input from last week’s tests and we understand that the team planned it way in advance. The Week 1 car was a representation of where the design was at in the wind tunnel by the end of November and was built as a ‘safe’ option for the first week of testing, to insure against there being any delays with the development of the more aggressive package.
The build of this ‘safe’ initial car allowed the aero department to continue working in the wind tunnel on the original more aggressive concept for several more weeks, the result of which is the car that broke cover on Tuesday of Week 2 and which essentially is the car that will be raced in Melbourne.
That one piqued my interest. Pretty remarkable stuff.dans79 wrote: ↑28 Feb 2019, 01:34The most interesting comment imo, is this one.zibby43 wrote: ↑27 Feb 2019, 22:20Very interesting technical piece by Mark Hughes

Surely there is no chance any team has no issues to iron out.De Jokke wrote: ↑28 Feb 2019, 00:41My gut feeling remains the same: Merc is behind.
